| * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka. * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets. * Hirata-san worked on organizing: * Checking Mirapro assembly frame drawings * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM) * Work platforms and clean booth second floor arrangement. * Load gauge adapter and associated parts * Possible fall-back plans for the rods connecting the security structure to the PI. * Design for additional trim masses (existing design had no provision for adding/removing). |
* Fabian, Mark and Liu-kun did BS installation at Kamioka: * Built up the security structure to the ring below the BF. * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF. * Craned in the BF. * Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.) * Hirata-san: * Made 3D models of (revised) stub flag gluing jigs. * (For other groups) * Assembled two BFs. * Made drawings of PRM inner frame. * Mark checked lots of drawings by Hirata-san. * Mark worked on schedule. * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors was completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which corrects them. * Longer term to-do list * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing. * Part "disk security" top has to be modified - screw positions do not match. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) - TM/IM/BF level DONE * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) |

- Type B Past Week Summary
- Fabian, Mark and Liu-kun did BS installation at Kamioka:
- Built up the security structure to the ring below the BF.
- Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
- Craned in the BF.
- Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.)
- Hirata-san:
- Made 3D models of (revised) stub flag gluing jigs.
- (For other groups)
- Assembled two BFs.
- Made drawings of PRM inner frame.
- Mark checked lots of drawings by Hirata-san.
- Mark worked on schedule.
- Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors was completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which corrects them.
